IR shooting with Canon 7D?

[Scott1970]

Does anybody here do infrared photography with the Canon 7D body?

I bought a Sing-Ray infrared filter, and I've tried a few times to get some infrared shots out of it (blue sky with a few clouds and lots of green foliage).

I set the camera up on tripod, get a focus on the scene then lock it, screw on the filter, and take the photo.

I expect to get a high-contrast sky against the clouds, and the ghostly white look to the foliage when i convert to greyscale in photoshop, but what I end up with is very bland and disappointing. The photo doesn't really look much different than if I converted a standard photo to greyscale -- the foliage is not white, but grey, and the skies are not very contrasty.

When i shoot, I set for several stops of overexposure; if i let the camera set the exposure with the filter in place, what is indicated as a proper exposure looks totally black.

Am I doing something completely wrong, or is the IR blocking filter in the 7D just too good, so that enough red light leaks in to ruin the IR effect?

If you shoot IR with the 7D, and get good results, could you be so kind as to explain how you do it, please?

Can you post some examples? Some of the newer cameras have had really strong IR blocking filters. My A700 worked quite well for IR, my A900 is terrible for it.
